英文摘要 | PURPOSE:To allow a semiconductor laser element to have a higher output, by a method wherein inside a resonator a refractive difference is provided laterally, while in the vicinity of the resonator end surface, light is dispersed toward the outside. CONSTITUTION:The layer having an opposite polarity for restricting a current passage is subjected to etching in order to cut a stripe groove as that the stripe width will be small in the vicinity of resonator end surfaces 20, 21 but large inside the resonator. A crystal layer for laser oscillation is deposited on the surface having the stripe groove. The thickness of an active layer 17 or light- guide layer constituting the crystal layer is formed thick correspondingly to the stripe groove inside the resonator. On a P-GaAs substrate 14, a current-trapping layer 15 made of n-GaAs for restricting the current passage, a P type clad layer 16 made of P-GaAlAs, an active layer 17 made of P- or N-GaAlAs (or GaAs), and N type clad layer 18 made of N-GaAlAs, and an cap layer 19 made of N- GaAs are successively laminated by liquid phase epitaxial growth. |
